Steely Dan's Aja (33 1/3 Series)

Aja was the album that made Steely Dan a commercial force on the order of contemporaries like Fleetwood Mac, the Eagles and Chicago. A double-platinum, Grammy-winning best seller, it lingered on the Billboard charts for more than a year and spawned three hit singles. Odd, then, that its creators saw it as an "ambitious, extended" work, the apotheosis of their anti-rock, anti-band, anti-glamour aesthetic. Populated by 35 mostly jazz session players, Aja served up prewar song forms, mixed meters and extended solos to a generation whose idea of pop daring was Paul letting Linda sing lead once in a while.
